Patent CA-2614812-A1 (CA)
Inventor: WOODWARD NATHAN G
IPC: F04B23/08
Filed: 2001-06-28
Abstract: A flywheel energy storage system (200), includes two pumps (218, 224) arranged in parallel for simultaneously drawing-off and absorbing substantially all of the gases that evolve from a flywheel assembly during high speed operation. A water sorbent (224) has the primary purpose of pumping water vapor and a getter pump (218) has the primary purpose of pumping active gases. The parallel pumps, i.e., the water sorbent (224) and getter pump (218) are disposed in a gas storage chamber (214) that is separate from the main housing (202) of the flywheel system. A drag pump (216) pumps evolved gases from the main housing (202) to the gas storage chamber. Since the water sorbent has a relatively fast pumping speed as compared to the getter pump, getter material used with the getter pump degrades at a substantially slower rate thereby reducing the cost of using the getter pump.

Title: Self-detection of a modulating carrier and an optimum carrier in a downhole telemetry system
Inventor: KYLE DONALD G
IPC: E21B47/12
Filed: 2008-01-22
Abstract: Self-detection of a modulating carrier and an optimum carrier in a downhole telemetry system. A method of detecting a carrier frequency in a downhole wireless telemetry system includes the steps of: transmitting from a first telemetry device a message modulated on a predetermined carrier frequency; receiving at a second telemetry device signals including multiple frequencies;  and selecting from among the multiple received frequencies the predetermined carrier frequency on which the message is modulated. A method of detecting a usable downhole wireless telemetry system carrier frequency includes the steps of: transmitting from a first telemetry device a message modulated on a carrier frequency; then checking whether a response to the message is received at the first telemetry device from a second telemetry device; and each time the response is not received, repeating the transmitting and checking steps with an incremented carrier frequency.

Title: Wireless communication method and apparatus for detecting and decoding enhanced dedicated channel hybrid automatic repeat request indicator channel transmissions
Inventor: YANG RUI
IPC: H04J1/16
Filed: 2006-08-04
Abstract: A wireless communication method and apparatus for detecting and decoding enhaiced dedicated channel (E-DCH) hybrid automatic repeat request (H-ARQ) indicator channel (E-HICH) transmissions are disclosed. A wireless transmit/receive unit (WTRU) receives E-HICH transmissions (202) and detects an H-ARQ indicator transmitted via the E-HICH by performing a binary hypothesis test (204). The WTRU then generates an acknowledgement (ACK) message or a non acknowledgement (NACK) message based on the detected H-ARQ  indicator (206). A reliability test may be further performed to improve performance, whereby the binary hypothesis test may be performed only if the reliability test is passed.

Abstract: A system for locking the wheels of a dolly for a cleaning device has a brake arm that has one end that is hinged to the base of the dolly. The brake arm pivots between a disengaged position and an engaged position where a stop on an opposite end of the brake arm engages the circumference of one of the wheels on the dolly. A spring biases the brake arm to the disengaged position. The spring can be mounted on a pin that is seated on the base and extends through a slot in the brake arm. An operator-engagable lever is used to move the brake arm from one position to another. The lever can be hinged to the pin, pivoting into and out of a locked position in which the lever presses the brake arm into the engaged position. A  cam surface on the lever is shaped so that moving the lever to one side of a critical point causes the lever to be biased toward the locked position, and moving the lever to the other side of the critical point causes the lever to be biased toward the unlocked position. The part of the lever that abuts the brake arm when the lever is in the locked position can be a flat section on the cam surface.
